STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 279,419, dated. June 12, 1883.

Application filed April 20, 1882. (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN S. NEWTON, a citizen of the United States, residing at Binghamton, in the county of Broonie and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specificatiomreference being had therein to the accompanying drawings.

Figure 1 is an elevation, partly in section, of a bottle-stopper containing my invention, with the ports open; and Fig. 2 is a similar View with the ports closed.

In the drawings, A is a cylindrical dischargetube, provided near its upper end with a port, a.

B is an expanded head, provided with a fiaring portion, b, and a lower screw-threaded part or shank, k, which screws into the upper end of the discharge-tube.

O is a cylinder surrounding and fitting closely the upper portion of the discharge-tube, and provided at its upper end with a flaring flange, D, adapted to fit closely the part b.

H h is a flange projecting from the lower end of cylinder 0, the part It being parallel with the lower end of the discharge-tube.

I is a flange projecting horizontally from the discharge-tube, and adapted to cover a tubecork to be applied to the screw-threaded portion J of the discharge-tube.

z is a collar projecting upwardly from the flange I, and within the part 71.

E is a spiral spring surrounding the discharge-tube and within the collar 27, its upper end engaging with the under side of flange H, and serving to thrust cylinder 0 and flange D up against the part b of the head, and thus close the discharge-port a,which may be readily opened by pressing the cylinder and flange down into the position shown in the drawings. It will be seen that the flange h and collar 03 overlap each other, and thus screen the spiral moval therefrom.

What I claim is- 1. In a bottle-stopper, the combination of the discharge-tube A, having port a, the head B, sliding cylinder 0, and spring E, the head B being provided with the threaded shank k, engaging with the threaded upper portion of tube A, substantially as set forth.

2. In a bottle-stopper, the combination, with the discharge-tube A, having port (1 a flange. I, and a screw-thread, J, of the sliding cylinder 0, provided with flange H 11, and the spring E, interposed between flanges I H, substantially as set forth.

3. In a bottle-stopper, the combination,with the dischargetube A, haying port a, of the head B I), sliding cylinder having flange D, and the spring E, operating to thrust the cylinder (l and flange I) upward, substantially as set forth.

4. In a bottle-stopper, the discharge-tube A, having port a, and the flange I, made integral with the tube, the head B, detachably secured to the discharge-tube, the slidingcylinder 0, and spring E, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
